H3 Series mini-client small factor HTPC chassis has the heatpipe on the left instead of right comparing to H10/H5 HTPC chassis. The compatible motherboard list should not be mixed with the H5 and H10 fanless computer chassis although they use the same HDPLEX fanless heatsink system. The heatpipe in fanless H3 HTPC chassis fly over the PCIEx16 slot. The 24PIN ATX plug will not block the heatpipe path in H3 HTPC SFF case.

MB not on this list should also be compatible if they meet requirement on the compatibility page. This list will be periodically updated base on user feedback. microATX standard spec is 9.6"x9.6" but it also comes in small factor such as 9.6"x 8.3" or 9.6"x7.6". Small factor microATX mobo is recommended for better installation experience. It would allow more space for sata/power cable arrangement.

The optical drive on this list have been installed and tested by HDPLEX Inc. Other optical drive should also be compatible if they meet the above requirements. This list will be periodically updated base on user feedback.

A. Install the IR PCB in the IR slot on the back of the chassis faceplate using one M3x6 screw

B. HDPLEX Internal IR PCB wire layout.

C. Plug the USB on the motherboard internal port, plug the power switch cable on the middle two PIN of the HDPLEX power switch PCB.

D: Connect the 5VSB to the +5V output from the DC-ATX converter.

If you can’t power up the PC from S5 state, first unplug the IR switch cable, flip 180 degree and plug back. Incorrect polarization will prevent IR from power up the PC. If this does not solve the problem, you need to use HDPLEX IR’s unique “Forced shutdown” function. See details in the “Multimedia function” section.

Part 2: Remote Configuration
The HDPLEX MCE remote is preconfigured as the standard windows MCE remote and use Microsoft Windows native driver, no third party driver is needed.
In addition, remote configuration program allows you to tailor the MCE remote to your needs. Download this program at http://hdplex.com/images/accessories/remote.zip

To assign a function, just click the corresponding key to activate setup window. A warning dialog box will pop up if the program does not detect the HDPLEX internal IR. Please make sure the IR is plugged properly on the motherboard USB port. If you continue with this warning, no setup will be saved.

There are six categories of functions which you could assign to a remote key.

Standard keyboard function

Multimedia function (For OS):

Forced Shutdown function: This HDPLEX IR unique feature allows you press and hold the key for 4-5 sec and PC will be shut down while the OS is not responding. In addition, some motherboard could not be powered on by USB port in S5 state (power off state). Assign “Forced shutdown” and press and hold the key for 4-6sec, the HDPLEX internal IR will perform a hard power on action, the same as physically press the power button to start the PC.

Windows MCE function:

Mouse and Command Line Function:

Switching Profile function:

Part 3: Using Profiles

HDPLEX IR allows each key have four different function by switching between four profiles. For example, key”1” could function as keyboard “P” under profile 1 and “Volume+” under profile 2.

Profiles could be exported and imported in the format of BIN file.
Each individual profile could be exported or imported. For example, if user A export “Profile 1” to 1.bin and user B import 1.bin to his profile 1, both users will have the same remote key function under Profile 1. If user B import 1.bin to his “Profile 2”, his other three profiles won’t be affected and his profile 2 will have the same remote key configuration as user A’s profile 1.

All four profiles could be exported or imported at once as a single bin file when choose “All Profiles”. For example, user A export his four profiles into foursettings.bin. If user B import foursettings.bin when choosing “All Profiles” , user B four profiles will be the same at user A.
If user B import foursettings.bin when “choosing Profile 3”, only the first profile from foursettings.bin will be imported. In this case, user B’s profile 3 will be the same as user A’s profile 1.

Warning: “Empty current settings” button will erase key configuration for ALL FOUR PROFILES no matter which profile you have selected. If you want to get back to factory default, please download factory default settings at http://hdplex.com/images/accessories/factory.bin and import under “All Profiles”.

Zotac is showing an WiFi ready Sandy Bridge H67 mini-ITX Motherboard with 2 onboard USB3.0, SATA 6.0, and PCIEx16 Slot. This mini-ITX board seems to have better configuration than the rest H67 mini-ITX line up from other manufactures such as Gigabyte or ASUS. I hope Zotac will use UEFI Bios as well.

Since Zotac H67 mini-ITX has the same layout as the Zotac H55 mini-ITX motherboard, it should be compatible with the HDPLEX H5 and H3 series fanless silent HTPC case.
